What is Telecommunication Fraud?

Telecommunication fraud attacks voice, SMS and data services. Plays include SIM swaps and cloning to intercept OTPs; PBX toll fraud into premium routes; subscription fraud using stolen identities; and SMS pumping that exhausts OTP budgets using bot farms. Costs appear in write‑offs, chargebacks, and irate users.

Signals include: unexpected SIM/IMSI changes; spikes in calls and messages to high‑tariff destinations; new devices being authenticated with an immediate password reset; and bursts of traffic from suspicious ASNs. Support teams are bribed or coerced to “help” by bypassing controls.

Controls include: de‑emphasizing SMS for high‑value authentication; detection of SIM changes and chilling of sensitive actions; binding of accounts to known devices; and, when identity is in question, re‑prove the human using identity verification. For the payment edges (top‑ups, premium content), use payment fraud prevention services tuned to these actions. Telecom is a honeypot for social engineering — train staff and log everything.

Protect the number, protect the wallet.
